The England international wants Blues owner Roman Abramovich to take advantage of the club's transfer embargo reprieve and purchase players in a bid to strengthen their squad and widen the gap between them and their title rivals.
January will see an exodus of Chelsea stars as at least four of their key players will be on international duty at the African Cup of Nations and Terry sees it as a good opportunity to buy up and forge ahead towards the Premiership.
"It's good news. We lose four good players in January anyway. I'm sure the club and the manager are looking into that and having good talks with Roman," said Terry.
"I wouldn't be surprised if we do go out and buy because we don't know what's going to happen in the summer or the following summer.
"We're going well at the minute and we're lucky enough to have a big squad with good players who can come in if we get a couple of injuries.
"Looking at it realistically, we're maybe going to be suspended in the summer window and maybe another one after that. The manager has great experience and he knows what we need."
